I suspect the realistic bottom for this bitcoin "crash"/ correction is at 4500/4800 dollars. To back up my statement I am showing you that bitcoin has broken trough the 6000 dollar support and is "free falling" towards the next, RSI looks bearish in the short term implying that we are heading towards 4500/4800 dollar price region.
RSI, As you can see I am displaying the RSI in the 1 week chart, The RSI is heading towards the same region as in the 2014 crash ( shown in the yellowish circles).
Like you are shown the RSI still has some way to go until the 2014 RSI levels.
This for me suggets that BTC will drop a bit more to 4.5k-4.8k region.
Now this is all speculation but I wanted to share my opinion and views on this matter.
Thank you and hope this helps you in future trades!
